The invention discloses a steel sheet pile cofferdam corner water stop connecting structure which comprises two corner steel sheet piles arranged at an angle, lock catch plates are formed on the two opposite sides of the corner steel sheet piles correspondingly, preset locking openings are formed in the lock catch plates, the lock catch plates on one sides of the two corner steel sheet piles are oppositely arranged, and the lock catch plates on the other sides of the two corner steel sheet piles are oppositely arranged. The preset locking openings of the locking plates on the other sides of the two corner steel sheet piles are buckled with the preset locking openings of the locking plates of the adjacent steel sheet piles. The adapting piece is connected to the lock catch plate on one side of one corner steel sheet pile in a welded mode, a newly-added lock opening is formed in the adapting piece, sealing grease is poured into the newly-added lock opening, and a preset lock opening of the lock catch plate on one side of the other steel sheet pile is buckled to the newly-added lock opening. The problem that a serious leakage phenomenon is prone to occurring at the corner connecting position of an existing steel sheet pile cofferdam is solved.

本发明公开了一种钢板桩围堰转角止水连接结构，包括：呈角度设置的两转角钢板桩，所述转角钢板桩的相对两侧分别形成有锁扣板，所述锁扣板形成有预设锁口，两所述转角钢板桩的一侧的锁扣板相对设置，两所述转角钢板桩的另一侧的锁扣板的预设锁口与相邻钢板桩的锁扣板的预设锁口扣合；以及转接件，焊接连接于一所述转角钢板桩的一侧的锁扣板，所述转接件形成有新增锁口，所述新增锁口内灌注有密封油脂，另一所述钢板桩的一侧的锁扣板的预设锁口扣合于所述新增锁口。本发明解决了现有的钢板桩围堰的转角连接处容易发生严重渗漏现象的问题。
